That's not (always) because they're homosexual, men holding hands in Arabic culture is more an indicator of equality and that both are actually paying attention to what the other has to say than sexuality.

Not entirely unlike the behavioral difficulty when an Arabic person tries to confide in a foreigner, by getting REALLY up close, and the foreigner (who likes personal space or has had friends recently exploded) takes it the wrong way.

The Iranians supported Khomeini because they thought he would just fade into the background, which is basically what he promised. When he arrived in Iran, he used his influence to squash any notion of a democratic and modern state and used the same kinds of goons the Shah had used to continue, and in fact deepen the oppression.

One can say a helluva lot of bad things against the Shah, but at least the man had a progressive vision. Khomeini, on the other hand, was a power hungry religious fanatic determined to turn back the clock. I doubt there are many Iranians of the Revolution generation who probably feel inviting Khomeini back to Iran was a very good idea.
